360-degree video for large scale navigation with 3d interactable models

ABSTRACT

A method and system for authoring a three-dimensional (3D) presentation can involve dividing a scene into a grid of equals-sized segments or non-equally sized segments, wherein one or more 360-degree cameras record the scene from a center of each segment, and a size of the each segment is proportional to a complexity of an environment captured in the scene. One or more objects can be created within the scene for a user interaction with a 3D presentation of the scene in the context of a video stream. A logical center of the object(s) can be used as a center point for recording a 360-degree video by the one or more 360-degree cameras for use as a low fidelity background video when the user interacts with the 3D presentation of the scene. The 3D presentation can be based on a 3D model.

CROSS REFERENCE TO RELATED APPLICATIONS

This patent application is a continuation of U.S. patent application Ser. No. 16/779,444 filed on Jan. 31, 2020, which is herein incorporated by reference in its entirety.

TECHNICAL FIELD

Embodiments are generally related to industrial automation systems, and more particularly, to the visualization of industrial data. Embodiments further relate to the field of authoring AR (Augmented Reality) and VR (Virtual Reality) applications. Embodiments further relate to paid authoring three-dimensional (“3D”) presentations.

BACKGROUND

Generally, augmented and virtual reality technologies allow users to experience content in 3D using some kind of display (e.g., in a head-mounted or hand-held device) capable of presenting virtual 3D environments from different perspectives. For example, a head-mounted or hand-held display might present a 3D scene from a perspective that changes depending on the orientation of the display. Augmented reality systems can combine real and virtual objects to allow the two to interact. For example, augmented reality systems can layer digital content on top of real world content appearing in the display. Some augmented reality systems utilize a headset that allows a user to view the real world through a transparent optical component (such as a lens) while 3D virtual images are projected and reflected toward the user's eye, effectively overlaying the 3D virtual images on top of what the user sees in the real world. A 3D environment can be generated that includes a 3D model of the real world and 3D assets representing virtual objects. As such, the 3D environment can be used to manage the relationship between the 3D assets and the real world, and the 3D assets can be used to project 3D virtual images that appear to interact with the real world.

Conventional AR or VR applications (referred to collectively herein as “VR/AR applications”) can be accessed by a user via a wearable computer or other client device. Such AR/VR applications can generate and provide 3D presentations such as VR/AR presentations that can include three-dimensional (3D) holographic views of a plant facility or a location within a plant facility (e.g., a work area, a production line, etc.). The holographic views can be delivered to a wearable visualization computer, which renders the 3D view as a function of the user's current location and/or orientation. A VR/AR application can render a scaled down view of the factory floor area, which affords the user an external overview of the area. This external view may include real-time avatars representing human operators, superimposed production statistics and status data, and other information.

When authoring AR/VR applications that require users to navigate around, and interact with, extremely large-scale scenes, it is very difficult and time consuming to author these applications. Most solutions either completely create all the objects within the scene as 3D models, which is very time consuming and costly, or leverage 360-degree pictures for navigating around the scene, which is quick but has limited interactions, usually restricted to primitive two-dimensional (“2D”) overlays.

What is needed is a solution that provides the rapid authoring and low cost of 360-degree pictures/videos but also includes the interaction and fidelity of 3D models. This is important for rapid development of 3D modeling of large scale and objects rich scenes like modeling an entire industrial plant.

For example, the host and client devices can be any kind of computing device capable of facilitating augmented reality and/or virtual such as the computing device 1700 of FIG. 2.

More specifically, the host and client devices can be a head-mounted display (e.g., a VR or AR headset), a personal computer (PC), a laptop computer, a workstation, a mobile computing device, a PDA, a cell phone, a combination thereof, or the like. In an embodiment, at least one host or client device can be an AR headset or a VR headset such as a head-mounted display. Although embodiments below are described with reference to multiple AR and/or VR headsets, any combination of devices is possible.

Generally, the components of the 3D presentation system 100 can communicate with each other via, network 150, which may include, without limitation, any wired and/or wireless protocol (e.g., HDMI, USB, WiFi, Bluetooth, etc.). Additionally, and/or alternatively, network 150 may include one or more local area networks (LANs) and/or wide area networks (WANs). Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets, and the Internet. Although the components of the 3D presentation system 100 are described in the context of a host-client configuration, other variations of communication techniques and configurations will be understood by those of ordinary skill in the art and may be implemented within the present disclosure.

Referring to FIG. 2, an exemplary operating environment for implementing an embodiment is shown and designated generally as computing device 1700. Computing device 1700 is but one example of a suitable computing environment and is not intended to suggest any limitation as to the scope of use or functionality of the invention.

The bus 1710 represents what may be one or more buses (such as an address bus, data bus, or combination thereof). The various blocks of FIG. 2 are depicted with lines for the sake of conceptual clarity, and other arrangements of the described components and/or component functionality are also contemplated. For example, one may consider a presentation component such as a display device to be an I/O component. Also, processors have memory. We recognize that such is the nature of the art and reiterate that the diagram of FIG. 2 is merely illustrative of an exemplary computing device that can be used in connection with one or more embodiments. Distinction is not made between such categories as “workstation,” “server,” “laptop,” “hand-held device,” etc., as all are contemplated within the scope of FIG. 2 and reference to “computing device.”

Computing device 1700 typically includes a variety of computer-readable media. Computer-readable media can be any available media that can be accessed by computing device 1700 and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable media may comprise computer storage media and communication media.

Computer storage media include volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer-readable instructions, data structures, program modules or other data.

With reference to the 3D presentation system 100, embodiments described herein can support authoring and presenting 3D presentations in augmented reality and/or virtual reality. The 3D presentation system components refer to integrated components for authoring and presenting in augmented reality. The integrated components refer to the hardware architecture and software framework that support functionality within the system. The hardware architecture refers to physical components and interrelationships thereof and the software framework refers to software providing functionality that can be implemented with hardware embodied on a device.

The end-to-end software-based system can operate within the system components to operate computer hardware to provide system functionality. At a low level, hardware processors execute instructions selected from a machine language (also referred to as machine code or native) instruction set for a given processor. The processor recognizes the native instructions and performs corresponding low-level functions relating, for example, to logic, control and memory operations. Low-level software written in machine code can provide more complex functionality to higher levels of software. As used herein, computer-executable instructions includes any software, including low-level software written in machine code, higher level software such as application software and any combination thereof. In this regard, the system components can manage resources and provide services for system functionality. Any other variations and combinations thereof are contemplated with embodiments. Note that such computer-executable instructions can include instructions for implementing steps or operations such as the steps or operations illustrated and described herein with respect to the various blocks shown in FIG. 3, FIG. 4, FIG. 5, and FIG. 6.

By way of example, the 3D presentation system 100 can include an API library that can include specifications for routines, sub-routines, data structures, object classes, and variables, which may support the interaction between the hardware architecture of the device and the software framework of the 3D presentation system 100. These APIs can include configuration specifications for the 3D presentation system 100 such that the different components therein can communicate with one another in the 3D presentation system 100, as described herein.

As will be discussed, the disclosed embodiments can provide a solution involving the rapid authoring and low cost production of 360-degree pictures/videos and can also involve the interaction and fidelity of 3D models. This solution can be used for the rapid development of 3D modeling of large scale and object-rich scenes in applications such as, for example, modeling an entire industrial plant or facility.

The disclosed approach can include rapidly authoring extremely large-scale scenes using 360-degree videos with hotspots (e.g., transport points) for navigation around the scene. This approach can also include interaction hotspots for transitioning to 3D models of objects that the user can then interact with. When a user has finished interacting with the 3D models, the user can be transitioned back into the 360-degree video and can continue navigating around the scene. In the scene, the user can be provided with visual cues that indicate where 3D immersive models jump-points are located. Within the 360 video, the user can view and navigate the scene and observe the surrounding, which can contain informational cues. When transported to a rich immersive model hotspot, the user will be able to have interactive capabilities with the model presented.

The large-scale scene can be broken up into a grid of equal sized segments, and 360-degree cameras can be used to record the scene from the center of each segment (i.e., high fidelity). The size of the segments can be proportional to the complexity of the environment. More detail may require smaller segments, and less detail can use larger segment sizes.

Objects within the scene that may be needed to provide user interaction can be created as 3D rich and immersive models. Note that navigating the 3D model of an object is inclusive of a deep dive (immersive) into the object seeing its internal construction, allows decomposing the object, seeing critical parameters that the object represents, configure the object, troubleshoot the object, etc. Basically, the 3D model can be an object that a user can interact with and deep dive into its construction or its functionality. This can be used as a learning mechanism of what the 3D model object represents. The logical center of each object can be used as a center point for recording a 360-degree video that can be then used as the low fidelity (low LOD) background when the user interacts with this 3D model.

The 360 videos can also contain visual cues. A user can navigate between hotspots (i.e., a position of each 360-degree camera) using a teleport type method that can rapidly translate the user's position, from the current hotspot, thereby providing a small amount of motion blur as the video stream is transitioned to the new camera position and video feed, which can then become the user's new position. This teleporting method can provide advantages over allowing the user to freely navigate around the environment. Such advantages can include, for example, reduced motion sickness for the user, a limited need for interpolating video positions between hotspots during translation, and simplicity of implementation.

Since the entire scene can be mapped out, the position of each interactable object can be known in world space, as well as the optimal position (e.g., a hotspot) from which to allow the user to initiate the interaction with that object. At this hotspot, an additional interactive asset (e.g., a button or similar visual element) can be overlaid in front of the image of the object.

If the user interacts with this asset, the current 360-degree video can be faded out and replaced with the low fidelity background video associated with the object. At the same time, a 3D model of the object can be constructed in the background and then faded into the position that the object (or objects) had occupied in the original 360-degree video. Since the position of the original object, relative to the user's position (hotspot) may be known, the 3D model of the object can be placed into the world space in such a manner as to appear seamless from the user's perspective.

The user may now be able to interact with the 3D model of the object, including freely moving within the segment, as well as around the 3D model. When the user has completed the interaction with the 3D model, the user can return to the hotspot position they started at, when interacting with the 3D model.

From this position, the user can interact with a button that can take the user back to the 360-degree video. The low fidelity background 360-degree video and the 3D model can be faded out from the scene. The 3D model can be deleted, and the high-fidelity 360-degree video can be faded back into the user's view and resumed.

The user can now navigate around the scene as before. The solution may not be limited to one user at a time. That is, the full scene navigation can support 1 to N number of users where such users can observe or interact with each other's avatars in the virtual space.

FIG. 3 illustrates logical operational steps of a method 300 for authoring a 3D presentation involving dividing a grid of equal-sized segments, in accordance with an embodiment. Note that the authored 3D presentation created as a result of implemented the various methods disclosed herein can be presented via a 3D presentation system such as the 3D presentation system 100 discussed earlier.

As depicted at block 302, a step or operation can be implemented in which a scene can be divided into a grid of equal-sized segments and a 360-degree camera used to record the scene from the center of each segment (i.e., high fidelity). Note that although a step of dividing a grid of equal sized segments, can be implemented, as discussed above, it can be appreciated that a more complex scene stitching algorithm can allow non-equally sized 3D video segments to be stitched together. Next, as described at block 304, a step or operation can be implemented in which one or more objects within the scene is created for user interaction with a 3D presentation of the scene in the context of a video stream. Note that the term “video stream” as utilized herein can relate to “video streaming,” which is a type of media streaming in which the data from a video file is continuously delivered via the Internet to a remote user. Video stream can allow a video to be viewed online without being downloaded on a host computer or device.

As illustrated next at block 306, a step or operation can be implemented in which the logical center of the object can be used as a center point for recording a 360-degree video by the 360-degree camera for use as a low fidelity background video when the user interacts with the 3D presentation of the scene, and wherein the 3D presentation is based on a 3D model.

FIG. 4 illustrates logical operational steps of a method 400 for authoring a 3D presentation involving a teleporting technique, in accordance with an embodiment. The term “teleporting” or “teleport” as utilized herein can relate to the so-called “teleport effect”, which may involve changing the orientation of a user with the virtual space of a VU (Virtual Universe). A VU can be implemented as a computer-implemented simulation intended for its users to traverse, inhabit, and interact through the use of avatars. Many VUs are represented using 3-D graphics and landscapes, and are populated by many thousands of users, known as “residents.” VUs (virtual universes) are traversed by such methods as walking, flying, and teleporting.

A teleport can provide a mechanism to travel rapidly from one location in a VU to another location, even if the locations are geographically far apart. In typical virtual universes, an invitation for teleporting may be received that is an offer to transport the recipient from a recipient's current location to a second location. A user may reject or accept the offer for teleporting. If the user accepts the offer, for example by selecting the invitation presented as words on the VU GUI, the user's avatar is then transported from the current location to the second location. In practical terms, teleportation (and hence, “teleporting” and “teleport”) can refer to the “re-rendering” of an avatar in a different environment. This re-rendering may occur on the same processor within the same simulation engine; it may occur on a different processor within the same simulation engine; on the same processor with a different simulation engine; or a different processor with a different simulation engine.

Note that the method 300 and the various steps and operations of the method 300 can be implemented following implementation of the method 300 depicted in FIG. 400. For example, the step or operation shown at block 402 can be implemented following implementation of the step or operation discussed above with respect to block 306.

As shown at block 402, a step or operation can be implemented to allow a user to navigate between hotspots in the 3D presentation using a teleporting method. Next, as shown at block 404, the teleporting method can include translating the position of the user from a current hotspot. As depicted next at block 406, the teleporting method can further involve providing motion blur as the video stream is transitioned to a new hotspot, which becomes the new position of the user. Note that the various methods 300, 400, 500 and 600 illustrated and described herein with respect to FIG. 3, FIG. 4, FIG. 5, and FIG. 6 can implemented as part of an overall method or process. For example, the method 400 may be implemented after method 300, and so on.

FIG. 5 illustrates logical operational steps of a method 500 for authoring a 3D presentation involving an overlaying operation, in accordance with an embodiment. A shown at block 502, a step or operation can be implemented to overlay at a hotspot an additional interactive asset (e.g., a button or a similar visual element) in front of the image of the object. The step or operation depicted at block 502 in FIG. 5 can be implemented after implementation of the step or operation shown in block 406 of FIG. 4, as discussed above.

Next, as depicted at block 504, a step or operation can be implemented in which if the user interacts with the asset, the current 360-degree video can be faded out and replaced with the low fidelity background video associated with the object. Thereafter, as illustrated at block 506, a step or operation can be implemented to simultaneously, construct the 3D model of the object in the background and fade into the position that object had occupied in the original 360-degree video. Then, as shown at block 508, a step or operation can be implemented in which the user can now interact with the 3D model of the object, including freely moving within the segment, as well as around the 3D model. Regarding the operation depicted at block 508, as discussed previously, navigating the 3D model of an object is inclusive of a deep dive into the object seeing its internal construction, allows decomposing the object, seeing critical parameters that the object represents, configure the object, troubleshoot the object, etc. Basically, the 3D model is an object the user can interact with and deep dive into its construction or its functionality. This can be used as a learning mechanism of what the 3D model object represents. Next, as indicated at block 510, when the user has completed the interaction with the 3D model, the user can return to the hotspot position he or she started at, when interacting with the 3D model.

FIG. 6 illustrates logical operational steps of a method 600 for authoring a 3D presentation involving a fading operation, in accordance with an embodiment. Method 600 can be implemented following implementation of method 500. For example, the operation shown at block 602 can be implemented after implementation of the step or operation shown at block 510 in FIG. 5. Thus, as shown at block 602, from this position, the user can interact with a button that will take the user back to the 360-degree video. Next, as depicted at block 604, a step or operation can be implemented in which the low fidelity background 360-degree video and the 3D model are faded out from the scene. Thereafter, as illustrated at block 606, a step or operation can be implemented to delete the 3D model and fade the high-fidelity 360-degree video back into the user's view. Next, as shown at block 608, a step or operation can be implemented in which the user can now navigate around the scene as before.
